This does happen to many. Icons are missing or disappear, reappear: This
happens for most Auto-Logon users.
Methods/workarounds: Log off and Log back on, password protect your account
or disable SSDP and uPNP Services.
Disable SSDP and uPNP Services (Line 156)

Or if you are running XP SP1 uninstall UPnP from Add/Remove Windows
Components.
Added info:
Remove Past Items From the Notification Area (Line 53)
http://www.kellys-korner-xp.com/xp_tweaks.htm
Once done, Open Task Manager, click the Processes tab, click Explorer.exe,
and then click End Process. In Task Manager, click File, click New Task,
type explorer, and then click OK.
The "Past Items" values are written to the registry as part of the user log
off process. This is why it is necessary to "crash" Explorer, so the system
will re-read the new values, and not retain the old ones that are already in
memory from a reboot.
Icons in the Notification Area May Disappear If You Use High-Contrast Color
Themes in Windows XP
